The problem seems to occur in in all browsers and is VERY annoying. I'm on LMDE 12 Update 4, on a Dell XPS 14Z. The Wifi chipset is Intel Centrino 6230 Wireless N capable. Here is my out put from iwconfig:

I have AT&T U-verse gateway that supports up to Wireless G. On my 9 year old laptop running Windows 7 I have an old Linksys Wireless G dongle plugged in and it maintains 100% signal strength to the wireless network. However, my LMDE laptop fluctuates wildly between 60% - 9x% Wifi signal strength. Sometimes browsing will go smoothly and then it will just "spin" waiting for response from the page. I can compare the same site on both laptops and the windows machine loads the page instantly and LMDE machine much slower. If I ping google from a terminal I do not get any packet loss and the response times are about 50 ms (same as on the windows machine). I'm not sure how to ts this at this point, but I need to get this fixed. Suggestions? Any help is appreciated.

Hmm. The WIFI signal still fluctuates between 50% - 95% after updating the to the latest drivers from the testing branch. Something still has to be going on. I find it absurd that when I'm in the same room as the Wireless router I do not have and maintain 100% signal strength. Any other ideas?
